SPECIFICATION forming part of Letters Patent No. 739,504, dated September 22, 1903.

Application filed April 8, 1903 $erialllo. 151,620. No model.) 7

To all whom, it may. concern: Be it known that I; R HARD R. PEARSON, a citizen of, the United States, residing at Seymour, county of NeWl-Iaven; State :of' Con ,necticut, have invented a new and useful Mop-Wringer, of which the following is a specification. a,

My invention relates, toqthe classofmop-i wringers adapted for. attachment to pails. 7 It is one of the objects of "the invention to provide a mopfwringer whose movable presser-board shall be free to oscillate in the vertical plane, so as to make it self-adjusting to the shape of the mop that is .to be squeezed.

Further objects of theinvention are to generally simplify and strengthen the, construc-v tion of the device as a whole, so as to reduce the cost of construction to the minimum, to

. add greatly to the durability, and to improve the mode of operation in general use. With these and other objects inview the invention consists in vcertain constructions and in certain parts, improvements, and com binations, which will be hereinafter described and then specifically pointed out in the claims,

. hereunto appended.

In the accompanying drawings, forming.

part of this specification, in which like characters of reference indicate the same parts, Figure 1 isan elevation of my novelmop-f wringer with the lever connection in section;

1O denotes the stationary presser-board, 11

I side pieces, and 12 a bottom piece, all of which is turned at an angle and engages an eye 17 upon an eyepiece 18, which is rigidly secured to a leg 19, itself rigidly secured to the outer 'side of the stationary presser board and adapted to engage the inner side of a pail in 'use, as clearly indicated inFig. 2. The eyepiece serves also as a retaining-clamp for a spring 20, one arm of which bears against the inner side of arm 15 and acts to throw the movable presser-board to the retracted position, as in full lines in Fig. 2. pre sser-board is operated by means of a tog- 'gle consisting of arms 21, extending from a rock-shaft 22, which is journaled in the side The movable pieces outside of the movable presser-board, and an arm "23, which is hinged to the outer end of arms 21 and is providedwith a rounded head 241, which. engages a socket 25 in the outer face of cross-piece 14:. The rock-shaft is oscillated by'means of a lever 26, which is rigidly secured thereto in any ordinary or preferredmannerfor example, as indicated in Fig. "1. Upon the inner faces of the side pieces are bearing-plates 27, through which .theiends of the shaft pass, said plates being provided with downwardlyextending hold ing-lu'gs 28, which passon the outer side of a :pail in use, and with stops 29, which limit the backward movement of the movable presser board, and one of said plates being pro- ,vided with a stop 30, the respective ends of which are adapted to be engaged by a double lug;31 on the rock-shaft to limit the oscilla- 8o tion of the rock -shaft in either direction. ,The rear ends of the side pieces are cut away,

so, as to form rests 32, (see Fig. 3, one rest' only. appearing,) which engage the top of a pail in use, and below the rests the side pieces 8 5 are inclined and beveled, as at 33, to adapt that portion of the side pieces to pass within apail. v I I In use the wringer is set over the edge of the pail, as indicated in Fig. 2, in which the 0 pail appears in dotted lines. Rests 32 on the side pieces engage the top of the pail, leg 19 engages the inner side of the pail, and holding-lugs 28 the outer side of the pail, so that there is no danger of the ringer becoming de- 5 tached from the pail in use. Spring 20 is strong enough to always retain the parts in the position shown in fulllines in Fig.2.

The use is the same as other devices of this character. The mop is placed between the presser boards and the 'movable presserboard moved inward toward the stationary presserboard by movement of the lever toward the right from the position shown in Fig. 2. Thisoscillates therock-shaft, straightens the toggle, and forces the movable presserboard toward the position shown in dotted lines, thereby squeezing the mop. The important difference between my improved mopwringer and others of its class is the self-adjustability of the movable presserboard, as illustrated in Fig. 4:, whereby it adapts itself to the thickness of a mop. where the ends of the presser-board must move uniformly that is, each must move the same distance, as in all former constructions of which I am aware-if the mop is not of uniform thickness the thick side will be squeezed, but no pressure whatever will be brought to bear upon the thin side. I11 my improved mop-wringer, however, the movable presserboard may oscillate freely in the vertical plane, owing to the fact that the engagement of the tip of arm 15, which carries the movable presser-board with eye 17, is a loose engagement and the engagement of rounded head 2% with the socket in cross -piece 14: is also aloose engagement. The movablepresserboard as it is moved forward is free to adjust itself to the thick and thin sides of a mop, so that thethin side of a mop will be squeezed as well as the thick side. As soon as pressure upon the lever is relieved the spring, through its engagement with arm 15, will return the movable presser-board and lever to the position shown in full lines in Fi 2, the return movement continuing until the presser-board engages the stops 29 upon the bearing-plates. Simultaneously, also, one end of lug 31 upon the rock-shaft will engage one end of stop 30, so as to hold the rock-shaft against further oscillation in that direction. The oscillation of the rock-shaft in the opposite direction is limited by the engagement of the other end of double lug 31 with the other end of stop 30.

Having thus described my invention, I claim 1. A mop-wringer comprising a stationary presser-board and side and bottom pieces, a movable presser board carried by a central arm and means for moving said movable presser-board inward, universal joints being provided at the lowerend of said central arm and at the connection between the movable board and the means for moving it, whereby said movable board is self-adjusting in the vertical plane.
